1196967-80-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1196967-80-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,6,9,6 and 7 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1196967-80:
(9*1)+(8*1)+(7*9)+(6*6)+(5*9)+(4*6)+(3*7)+(2*8)+(1*0)=222
222 % 10 = 2
So 1196967-80-2 is a valid CAS Registry Number.

Iodine-mediated guanidine formation through arylsulfonyl-activated thioureas
Qin, Cuiying,Li, Jizhen,Fan, Erkang
body text, p. 2465 - 2468 (2010/01/16)
Reaction of arylsulfonyl thioureas with amines to form guanidines can be efficiently promoted through the use of iodine, instead of conventional reagents such as the Mukaiyama reagent or EDC. The general scope and limitations of the reaction are probed.
